GEORGE J. FRITZ, OF ST. LOUIS, MISSOURI.

MACHINE FOR CORRUGATING METAL RCLLERS.

SPECIFICATION forming part of Letters Patent No. 369,239, dated August 30, 1887.

Application filed June 17, 1887. Serial No. 241,648. (No model.)

.To all whom, it may concern:

Be it known that I, GEORGE J. FRITZ, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Machines for Gorrugating Metal Rolls, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming partof this specification, and in which-- Figure I is a side elevation of a corrugating-machine provided with my improvement. Fig. II is a top view of same. Fig. III is an enlarged detail section taken on line III III, Fig. II. Fig. IV is a similar view showing a slight modification.

My invention relates to an attachment for machines for corrugating metal rolls; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims. I

Referring to the drawings, 1 represents the bed-plate of the machine, supported on suitable legs, 2.

3 represents a head provided withsuitable mechanism, 4, for holding a cutting tool, 5.

6 represents a block supporting one of the centers 7; and 8, a block in which isjournaled a shaft, 9, that forms the other center for supporting the roll 10.

The head 3, carrying the tool, is fixed to the bed-plate by suitable mechanism, (not shown,) and all of the parts that I have thus far described may be of any ordinary construotion.

11 representsa block or plate secured at 12 to one side of the machine, and which is provided with a groove, 13, to receive a projection, 14, on a perforated head, 15, through which passes a rod or shaft, 16, that is held from movement in the head by collars 17. The rod or shaft 16 is journaled to the bedplate of the machine by suitable boxes, 18, and it is threaded to engage a wheel, 19, on the shaft 9, that supports one end of the roller 10. The sides of the groove 13 are made serpentine or waving, as shown in Fig. II, so that as the plate 20, that carries the rollback and forth, andwhich is worked by suitable mechanism, moves back and forth, the projection 14, bearing in this groove, will, through means of the screw on the shaft 16 and the wheel 19, turn the roller 10 back and forth to give to the roller the serpentine or waving corrugation found in the groove 13, the objcct being to produce a roll having a serpentine or waving corrugation upon its periphery or surface. The form of irregularities upon the face of the grooves can be varied according to the form of corrugation desired on the roll.

Insteading of using the groove 13 and the projection 14, fitting therein, and as a modifition thereof, the head 15 may be provided with two projections, 14, fitting on the opposite sides of a rib, 2-1, on the plate 11, the rib corresponding with the groove 18, and which would be made waving or serpentine on its sides, as with the groove.

The projection 14 may be in the form of a roller journaled on a pin, 22, as shown in Fig. III.

I claim as my invention- 1. In a machine for corrugating rollers, in combination with suitable mechanism for supporting the roll and a suitable tool for cutting grooves or corrugations therein, the plate or block 11, formed with a groove, or its equivalent, with sides corresponding with the form of corrugation to be produced on the roller, and connection between the plate or block and the roller, whereby the latter is turned back and forth, substantially as and for the purpose set forth.

2. In a machine for corrugat-ing rollers, in combination with means for supporting the roller and means for supporting a cutter for corrugating or grooving the roller, the block 11, having a groove, or its equivalent, pro vided with irregular sides, head 15, having a projection engaging the groove, or its equivalent, shaft secured to the head, and connection between the shaft and the roller, whereby the latter is turned back and forth, substantially as and for the purpose set forth.

3. In a machine for corrugating rollers, in combination with mechanism for supporting the roller and mechanism for supporting a tool for corrugating or grooving the roller, the block 11, having groove 13, or its equivalent, provided with irregular sides, block 15, having projection entering the groove, or its equivalent, shaft 16, secured to the head and provided with a thread, wheel 19, meshing into the thread on the said shaft, and shaft 9, upon which the wheel is secured, and which supports one end of the roller, substantially as and for the purpose set forth.

In presence of- GEO. J. FRITZ.
